STEAM-G EN ERATOR.

SPECIFICATION forming part of Letters Patent No. 487,382, dated December6, 1892.

Application filed June 17, 1892. Serial No. 437,041- (No model.)

To all whom it may concern.-

Be it known that I, GEORGE VASSAR, Jr., of New York, in the county andState of New York,have inventedacertain new and useful Improvement inSteam-Generators, of which the following is a specification.

The object of my improvement is to provide a more desirable way ofsupporting boilers within the walls which inclose them.

I will describe a steam-boiler embodying my improvement and then pointout the novel features in the claim.

In the accompanying drawings, Figurel is a sectional side elevation ofasteam-generator embodying my improvement. Fig. 2 is a transversesection taken at the plane of the dotted line 2 2, Fig 1,looking in thedirection of the arrow, which is adjacent to such line. Fig. 3 is ahorizontal section of one of a number of upright beams or girders and aportion of one of the walls of the steam-generator. Fig. 4 is aninverted plan of a cap for such beam or girder.

Similar letters of reference designate corresponding partsin all thefigures.

A designates a boiler, which may be of ordinary or any other suitableconstruction. 13 designates walls inclosing such boiler or the mainportion thereof. Within these walls B a furnace C of any suitableconstruction is arranged.

At the front of the steam-generator there may be a wall of iron, andthis may be provided with doors in the usual manner.

D designates a number of upright beams or girders. As here shown, theyare made in the form generally known as I beams or girders, and arearranged in pairs connected by cross-pieces D, riveted or otherwisefastened to them. Caps D surmount each pair of beams or girders D andare provided on the under side with lugs for engaging with the tops ofthe beams or girders.

The configuration of the under side of the caps may be understood byreference to Fig. 4, and by considering this figure in connection withthe beam or girder represented in Fig. 3 it will be readily seen that byturning the cap over its transverse lugs will embrace the webs of thebeams or girders and its longitudinal lugs will fit against the oppositesurfaces of the flanges of the beams or girders.

The beams or girders may be made of iron or steel. This is also true oftheir caps. The lower extremities of the beams or girders may besupported on any suitable foundation of masonry or concrete. A pair ofthese beams or girders is shown as arranged on diametrically-oppositesides of the boiler near its front end, and other pairs are similarlyarranged near the rear end of the boiler.

Above the beams or girders D the boiler A is provided withlongitudinally-extending lugs A A which may be riveted or otherwisefastened in place. These are intended to cooperate with the caps of thebeams or girders for the purpose of sustaining the boiler independentlyof the walls. The lugs A rest directly upon the caps of the adjacentbeams or girders.

Between the lugs A and the caps of the beams or girders adjacent theretorollers A are arranged. These may simply be placed between these lugsandthe opposite caps, or they may be otherwise applied to provide for alongitudinal motion of the boiler relatively to the beams or girderswhich are beneath the lugs A and therefore prevent the boiler whencontracting orexpandinglongitudinallv from exerting any force tending totilt the beams or girders.

It will be seen that the pairs of beams or girders near the front end ofthe boiler are connected with the pairs of beams or girders near therear end of the boiler by means of tie-rods E. It will also be seen thattie-rods E extend from the front beams or girders D to the front wall ofthe steam-generator, and that tie-rods E extend from the rear beams orgirders to the rear wall of the steam-generator.

The tie-rods are shown as extending through the beams or girders. Thosewhich connect the front and rear beams or girders have heads at one endand nuts at the other end beyond the beams or girders. Those whichconnect the beams or girders with the end Walls are similar, in thatthey have heads at one end and nuts at the other. To afford an extensivebearing over the walls, they may also have plates interposed between thewalls and the nuts.

It will be seen that by my improvement I provide for constructing asteam-generator in such a way that this boiler will be supported ICOindependent-ly of the Walls, and hence it will be apparent that theWalls may be removed and reconstructed without disturbing the boiler.

What I claim as my invention, and desire to secure by Letters Patent, is

In a steam-generator,the combination, with a boiler and Walls inclosingthe same, of beams or girders supported independently of the walls andeach consisting of I-beams arranged in pairs and secured together, a caphaving lugs to engage the top of each pair of beams or girders, lugsextending from the boiler near the front and rear ends and sustained onthe tops of said beams or girders, and rollers intermediate of said lugsand the caps, substantially as specified.

In testimony whereof I have signed my name to this specification in thepresence of tWo subscribing witnesses.
